BOX FORM OR IMANDREL.

Application filed. April 28, 1922. Serial No. 557,148.

T 0 all 'whom t may concern Be it known that I, Mosns B. Diskrnya citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful.improvements in Box Forms 0r Mandrels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to forms or mandrels used in the manufacture of paper boxes, and the like, and aims to provide a novel and improved adjustable form or mandrel.

Another object of the invention is the provision of a box form or mandrel of novel and improved construction capable of adjustment whereby the device can be used for the making of boxes of different sizes of the same shape.

A further object is the provision of novel means for adjustably mounting the members which define the shape of the box, whereby they can be positioned for making boxes of different sizes.

A. still further object is the provision of a novel and improved adjustable bottom support for the box bottom, which is adjustable to correspond t0 the adjustment of the members which define and support the walls of the box.

It is also an object of the invention to provide such an improved boxform or mandrel which is comparatively simple and inexpensive in construction. which can be applied to various box making machines, which provides for the making 0f box forms in different shapes, .and which isr practical and eiiicient in use.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of the improved box-form, 'portions being broken away.

Fig; 2 is a section on the line 2 2 of Fig. l.

shaft for retaining `the form in place and permitting the form and shaft to be rotated relatively toone another.

` The form or mandrel is of skeleton construction, and the sides or walls of the box are defined by the side kbars 1e' parallel with the central supporting member 10, and said bars 14E, as shown in Figs. 1 and 2, provide the outline of a rectangular box, and the paper is wound on the form around the bars 111 to `give the box its shape. Each bar 14 is supported by a pair of crossed links 15 and 16, pivoted together at their point of crossing, as at 17. rlhe links 15 are pivoted to the bars 14:, as at 18, while the links 16 have studs or pins 19 engaging slidably in longitudinal slots 20 in said bars, to provide -for the adjustment of the bars 14 toward and away from the member 10 when the links are swung relatively to one another, keeping the bars 14C parallel with said member 10. The inner ends of the links are pivotally connected with plates 21 and 22 mounted on `the member 10, and these plates are of the shapel of the box to be formed, only smaller. rlhe plate 21 is secured in place on the member 10 by means of a set screw 23, while the plate 22 is adjustable toward and. away from the plate 21 in order to obtain the adjustment of the bars 14.

As shown, the plates 21 and 22 have slots 24 `in the edge portions thereof receiving the inner ends of the links 15 and 16, and said links have pivot studs or pins 25 seated in notches between the edge portions of the plates andretaining members 26 secured to said plates by means of bolts 27 or the like. The studs 0r pins 25 are thus pivotally anchored between the plates and retaining members, providing a convenient manner of pivotally assemblingthe links with said plates. 5

The adjusting means of the plate 22, as shown, includes a nut 28 screw-threaded on the member 10 and having a socket portion 29 receiving a boss SOof the plate 2,2, said, boss 'having an annular'l groove 31' receiving a sorew 32 carried by the socketportion 29, whereby the plate 22 is connected with the nut by a swivel joint, permitting the nut to be rotated for moving the plate 22 longitudinally on the member 10,

By adjusting the plate 22 away from the plate 21, the links are made to swing toward `the axis ofthe form, thereby moving the bars 14T toward the member 1), and reduc ing the size of the form, and, vice versa, when the plate 22 is adjusted. .toward the Vplate 2l, the bars 14 are moved away from the `member 10 to increase the size of the formjthe shape of the 'form remain-ing the samefin the several adj ustments. ln this way,

the form can be Aadj-usted for makingboxes justable support for the box bottom, `in

Ol A

line with'the ybars 14.

order' tol s'upport'the bottom while being fastened' to the side walls. Thus, the box bottom support includes aplate 33 of the saine shape t0 correspond' ywith the plates 21 and 22, andY having a central shank or stem 34 to/fit slidably in the member 10. for the longitudinal adjustment of the bottom suj'iportysaid shanlgr being` clamped 'in its adjL'isted position byl the setscrew 23,. 1 The plate 33 has grooves 35 in its outer face in which the extension bars 3,6 are slidable, said` grooves and bars being of dove-tailed crosss'ection to retain the bars in place, and the outerl ends of the bars are preferably pro. vided with heads 37 corresponding in out- A rlhe bars 3G are clamped in their adjusted positions by set screws 38`oarrie'd by the plate 3 3. The bars 8G are flush with the plate 33, .for supporting the box bottom. I y

After the bars have been adjusted accordi'ngto the size of box to be made,` the bars 36 are adjusted accordingly. and the lplat@ 33 isithen adjusted to bring Ithe headsv adjacent to the corresponding ends of the `bars 14. The'nfwhen the side walls ofl the box` are', formed onthe bars 14the box bottoni can be ,placed on or against the bottom support andthe adjacent edges of the box bottom and wallssecured together inthe well-known manner." j

Y The form ormandrel can be made indifferent shapes by uhaving the plates 21 and 221 of' various shapes, as l,shownl in Figs. 3,

@and and theseveral shapes of fdrmsor mandrels;areinterchangeablei Thus byr removing'fthetubular member l0 from the shaft 11, another form or mandrel can be quickly substituted on said shaft when a box of a different shape isu to be made.r Each' shape of mandrel is adjustable for the production of boxes of different sizes having the corresponding shape, and the forins'or mandrels can be used for making practicallyv all shapesof boxes, including square, rectangular, elliptical, circular, triangular and polygonal boxes. Ult will be noted ,that in each modification orshape of `.theform, the sidebars are arrangedy with ltheir outer edgesy extending outwardly away frointher axis of 'the central su j'ortin'fr member to.-

deine the outline of the form, said bars being dispos'edin radial planes in which the axis of the central supporting member is disposed. lThis isof advantageinstead of using broad youter surfaces for the meine j bers definingA the outline of thev forni, be.- cause in the difl'erentsizes of the form` the outer edges of side bars will give the paper its rproper shape whenv wrapped around theform, even when circular or elliptical forms are used`. y
